no....who was the guy on here that discovered an on electric heater behind a
partition ?

Not quite, but I did discover a heater towel rail (electric) in an
unused bathroom. I still don't know how long it had been on but, to be
honest, having removed it, there is little noticeable difference to
overall electricity consumption, which I record monthly.
